A small coil `C` with N = 200 turns is mounted on one end of a balance beam and introduced between the poles of an electromagnet as shown in Fig. The cross sectinal area of the coil is `S = 1.0 cm^(2)`, the length of the arm `OA` of the balance beam is `l = 30 cm`. When there is no current in the coil the balance is irl equilibrium. On passing a current `I = 22 mA` through the coil the equiibrium is restroed by putting the additional counterweight of mass `Delta m = 60 mg` ont he balnace pan. Find the magnetic induction at the spot where the coil is located.

When can a beam balance have static equilibrium?

A small coil is introduced between the poles of an electromagnet so that its axis coincides with the magnetic field direction. The cross-sectional area of the coil is equal to S = 3.0 mm^2 , the number of turns is N = 60 . When the coil turns through 180^@ about its diameter, a galvanometer connected to the coil indicates a charge q = 4.5muC flowing through it. Find the magnetic induction magnitude between the poles, provided the total resistance of the electric circuit equals R = 40 Omega .
